Netvibes like "draggable boxes" with javascript

Do you know any projec开发者_如何学JAVAt/framework in javascript (jquery or anything else) that has nice draggable windows that snaps in some fixed places like netvibes has? I found jPolite v2 but it seems a little too complex for what I want to do. Any idea?

You could use jQuery UI sortable. Look at the portlet example
